I would think that subduing suspects would literally be the cornerstone of a LEO's training. Without the ability to do that, you'd never be able to effect an arrest....effectively. There was also that incident about a year ago where the cop couldn't subdue a teenage girl and was standing there basically brutalizing her in front of a crowd while she struggled against him. You're telling me he couldn't have just swept her to the ground or put her in a hammerlock or something? But I digress.
